I suggest you ...

load pending changes UI window from plastic.exe

Ability to call the plastic.exe with --pending_changes to load up the pending changes UI (the same one used in windows shell extension). this will enable some easy integrations with other IDEs like VSCode and others that allow mapping a shortcut key to a command.

I'd expect to map a command in VS Code to the command "plastic.exe --pending_changes --workspace "e:\projects\my-vscode-project" and it would show me everything changed within that wrkspace and allow me to check the changes in.
